Porcine decellularized conjunctiva (PDC) represents a promising alternative source for conjunctival reconstruction. Methods of its re-epithelialization in vitro with primary human conjunctival epithel...
Bulbar conjunctival prolapse is one of the complications of conjoint fascial sheath (CFS) suspension and has a negative impact on surgical results. To explore the prevention methods of this complicati...
From January 2020 to August 2021, 81 patients with severe congenital ptosis who underwent CFS suspension were enrolled and divided into 2 groups. Forty-five patients' (Group A) CFS was dissected via t...
The incidence of bulbar conjunctival prolapse was 24.44% in Group A and 2.78% in Group B. Of the 12 bulbar conjunctival prolapse patients, 7 patients' conditions improved after conservative treatment,...
The incidence of bulbar conjunctival prolapse decreased significantly by dissecting CFS via the above-CBT approach. For patients with bulbar conjunctival prolapse after CFS suspension, bulbar conjunct...
This study aimed to investigate the microscopic structure and characteristics of nevi on the conjunctiva of the lacrimal caruncle by...
In total, four patients with nevi growing on the lacrimal caruncle conjunctiva were recruited. The morphological characteristics of the nevi were evaluated by...
The nevi of the four patients were all located at the conjunctiva of the lacrimal caruncle, with a slightly nodular surface, mixed black and brown color, and clear boundary. The nevi were round and hi...
This study revealed that the microstructure of nevi growing on the conjunctiva of the lacrimal caruncle can be identified by...
This study aims to determine the ultrastructural changes in collagen fibrils in rabbit conjunctiva after conjunctival crosslinking using riboflavin and ultraviolet A (UVA) light at an irradiation inte...
To report a rare case of primary sebaceous gland carcinoma of the bulbar conjunctiva without palpebral involvement....
A 76-year-old male was referred to the cornea service for a suspicious lesion on the limbal conjunctiva and cornea of his left eye. On exam, there was a large fibrovascular growth with conjunctivaliza...
Primary sebaceous gland carcinoma of the bulbar conjunctiva without eyelid involvement is a rare phenomenon. Our patient joins a few case reports in the literature. Of these cases, we are the second c...
The conjunctival epithelium covering the eye contains two main cell types: mucus-producing goblet cells and water-secreting keratinocytes, which present mucins on their apical surface. Here, we descri...
Pyogenic granuloma, also known as lobular capillary hemangioma, is a benign vascular lesion that primarily affects the skin and mucous membranes. It is not pyogenic; nor is it granulomatous. It typica...
The ocular surface in patients with atopic dermatitis (AD) is known to harbor an abundance of gram-positive cocci, particularly Staphylococcus aureus (S. aureus). This study reviewed the results of mi...
Retrospective, single-center study....
This study involved 131 eyes of 112 Japanese patients with AD (87 men and 25 women, mean age: 40.4 ± 12.2 years) who underwent ocular surgery at Kyorin University Hospital. Bacterial isolates were col...
One hundred and fifty-seven strains were identified in 103 of the 131 eyes examined. S. aureus was isolated from 74 eyes (56.5%), followed by Staphylococcus epidermidis (S. epidermidis). In S. aureus,...
Distinctive bacterial distribution and drug resistance need consideration in the managing of ocular disorders among patients with AD....
Bleb scarring is the most important complication of trabeculectomy. Changing the application position of mitomycin C (MMC) during trabeculectomy might affect the surgery outcome. Our aim is to compare...
This retrospective trial compared the surgical outcomes of 177 eyes that underwent trabeculectomy with adjunctive mitomycin C. In 70 eyes, an MMC-soaked sponge was applied under the scleral flap witho...
Within both groups, a highly significant IOP reduction was seen during follow-up. The effectiveness in reducing IOP and the change in best-corrected visual acuity (BCVA) were similar between the two g...
Since the effectiveness of IOP reduction was similar between both groups and with a low incidence of thin-walled blebs and hypotony, the subscleral application without touching Tenon's capsule seems t...
